  <gml:remarks>This is a parameter-less conversion to change the order of horizontal coordinates of a geographic 3D CRS.</gml:remarks>
  <gml:formula>The axis order change operates on coordinates of a point whose order change is described by the following matrix operation:

[Derived CRS 1st coordinate]        [ 0   1   0 ]     [Base CRS 1st coordinate]
[Derived CRS 2nd coordinate]   =  [ 1   0   0 ]  *  [Base CRS 2nd coordinate]
[Derived CRS 3rd coordinate]        [ 0   0   1 ]     [Base CRS 3rd coordinate]</gml:formula>
